Field Marshal Karl Mack von Leiberich (25 August 1752-22 December 1828) was a Field Marshal of the Austrian Empire who served as Quartermaster General to Ferdinand of Austria-Este. He surrendered a large army at the Battle of Ulm during the Napoleonic Wars in 1805, bringing shame to his military reputation.

Biography
A Bavarian by birth, Leiberich fought in the War of the Bavarian Succession from 1778 to 1779 and took Belgrade from the Ottoman Empire in 1789. He later fought in the French Revolutionary Wars and fought at the Battle of Neerwinden in 1793, and in 1797 he handed himself to the French to avoid being killed by his own men. He was released in 1800 with the peace that ended the Second Coalition and joined the Third Crusade as a Field Marshal and Quartermaster General for Ferdinand of Austria-Este. He was surrounded in the Battle of Ulm by Napoleon Bonaparte's army and surrendered over 70,000 Austrian troops without a major battle in 1805. He was paroled but strippled of title by the Austrians and jailed for two years. He was obscure until 1819, when Karl von Schwarzenburg reinstated his Order of Maria Theresa membership and his titles.
